Flow or Water Level	Percentile Range	Explanation
Low	0^th	The monthly mean streamflow or median water level during this month is the lowest ever recorded during the period of record for this site.
Much below normal	0^th to 10^th	The monthly mean streamflow or median water level during this month is less than the 10^th percentile when compared to all of the months during the period of record for this site.
Below normal	10^th to 25^th	The monthly mean streamflow or median water level during this month is between the 10^th and 25^th percentiles when compared to all of the months during the period of record for this site.
Normal	25^th to 75^th	The monthly mean streamflow or median water level during this month is between the 25^th and 75^th percentiles when compared to all of the months during the period of record for this site.
Above normal	75^th to 90^th	The monthly mean streamflow or median water level during this month is between the 75^th and 90^th percentiles when compared to all of the months during the period of record for this site.
Much above normal	90^th to 100^th	The monthly mean streamflow or median water level during this month is greater than the 90^th percentile when compared to all of the months during the period of record for this site.
High	100^th	The monthly mean streamflow or median water level during this month is the highest ever recorded during the period of record for this site.
